ASSESSING THE EFFICIENCY OF ALTERNATIVE BEST MANAGEMENT PRACTICES TO REDUCE NONPOINT SOURCE POLLUTION IN THE BROILER PRODUCTION REGION OF LOUISIANA A Thesis Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Master of Science in The Department of Agricultural Economics and Agribusiness by Bryan Gottshall B.S., Mercy College, 2009 December 2013 Acknowledgements I would first and foremost like to thank my parents Kathleen McLeod and Thomas Gottshall for their love and support throughout my life. Without the support of my family, I would never have made it anywhere in life, much less through graduate school. I would like to thank my major advisor Dr. Krishna Paudel for providing the opportunity to conduct this study as well as constant guidance and encouragement throughout. I would also like to thank my committee, Dr. Jeffery Gillespie and Dr. John Westra for their suggestions and guidance as well as Niu Huizhen for her help collecting data and creating the GIS layers. I would like to express gratitude for the constant help and support from my fellow students at LSU. In particular I’d like to thank Basu Bhandari, Abhishek Bharad, Luke Boutwell, Jill Christoferson, Madhav Regmi and Franklin Vaca for their constant academic support and therapeutic counsel. I am deeply indebted to Mahesh Pandit for his unending technical support. Finally, I would like to thank all of my friends who encouraged me to stick with this program despite my constant threats to quit. In particular I would like to thank Ian Smith, Zach Wilkerson and Roxanne Guidry for their unfettering friendship throughout this period. I would also like to thank my girlfriend, Missy Wilkinson, for her unending love, support and encouragement as well as her help in editing this thesis. ii Table of Contents Acknowledgements ......................................................................................................................... ii List of Tables .................................................................................................................................. v List of Figures ............................................................................................................................... vii List of Abbreviations ................................................................................................................... viii Abstract ........................................................................................................................................... x Chapter 1.
